The coolant in nuclear power plants is radioactive *mainly* because it has small amounts of insoluble stuff (commonly called "crud") suspended in it and soluble stuff dissolved in it that are radioactive, mostly Na-24 and Cl-38. Just a teeny little bit of cobalt from alloys in valves and pumps getting into the coolant and getting activated to Co-60 contributes a majority of the long-lived radioactivity of reactor coolant. There are some water activation products but they are smaller contributors and have short half-lives.
Those are all lower. They found this one point 50km out to the NW that had much higher levels than anywhere else. I don't think they're even sure it's from the nuclear plant.
I agree though, and they should include the level at the gate to the Fukushima 1 plant.
I still have a hard time remembering the significance of X sieverts. I was a nuclear trained submariner and we always reported dose in millirems/rems, and I have to tell myself that 1 rem is 10 millisieverts. I received just a little more than that in my 5 years of occupational radiation exposure, including some time inside the reactor compartment.
Well, I was last on a submarine 20 years ago. That is news to me. The articles mention the submerged endurance as being a few weeks which is definitely less than a nuclear sub, and since they are quite a bit smaller, their armaments are limited, but the technology certainly does seem to have some strong points. Learned something new today.
Liquid oxygen on a submarine? That's insane-- where'd you hear that? Subs have a snorkel mast they use to draw air in from above the sea surface when operating the diesel submerged. It's called snorkeling. It's either that or run on the surface. I was a nuclear trained machinist's mate on an SSBN so I stood watch in the Auxiliary Machinery Room 2 Lower Level and ran the diesel when it was needed (usually for reactor scram drills).
Depends on how thick it is, how it is anchored etc. In any case, it wouldn't work as long as the water flowed around it, I'm guessing, because it wasn't the impact of the wave that did the damage to the diesel generators, it's the fact that they were *underwater*. They do put snorkels on submarines to provide air to the diesel engine for operating the diesel while submerged close to the surface (it's called 'snorkeling'), but I don't think they did that on land.
Since the 'u' comes from the 'umami', wouldn't they be tssweet, tsbitter, tssalty, and tssour.
I know , I know, Japanese does not have a t or an s, or a ts, but it has a tsu and an u. Although when it comes at the end of a word, which is most common, the tsu sounds pretty much like 'ts'.
OK, this is funny: there is a word 'tsumami' in Japanese. It means pinch, as in shio hito-tsumami = pinch of salt
I think the earthquake was upgraded to 9.0 from 8.9 (at least by the USGS), so someone thought they see if IE could keep up, and lo and behold, it upgraded all the way from 1.0 to 9.0, ergo, more IE is more powerful than the earthquake.
You can't take your mod points with you into the past with a simple time machine, man! For that you'd need a temporal mod point transporter! That's seriously hard to imagine.
There was nothing wrong with the Chernobyl reactor...
Yes, there was: it had a positive temperature coefficient of reactivity. Water-moderated reactors have negative temperature coefficients of reactivity. It is a significant difference.
I think he's (she's?) agreeing with you, not trolling. You're both saying that it's human nature to be bad a risk assessment and to overreact to sensational low-risk things like nuclear power and terrorism, while being complacent about commonplace high-risk things like driving and food poisoning.
BPA (bisphenol -A) is not a plasticizer. It is the monomer from which polycarbonate is made. That's why those polycarbonate water bottles contain BPA. Residual (unpolymerized) BPA. Polycarbonate doesn't contain plasticizer. It's very rigid. Phthalates (e.g. dioctyl phthatlate, DOP) are common plasticizers.

But Einstein and Bose do go together.
Citation needed for whoosh.
Even if the productivity gain is small, so is the cost of a second monitor.

Because then they would become fragmented. Or something.
Trouble is, once you've broken the seal to read the EULA, you've bought it and you can't take it back.
Go back and read it again: 'regardless' and 'irregardless' were both used in the same post.
No, no , no. Alcohol is EtOH, not OTOH.
That used to be known as 'beer'.

Well, I get the joke, but the Nissan Leaf and Chevy Volt are partially nuclear-powered, depending on where you live.

Did they really mis-spell 'Stirling' in the wikipedia article? Wow.

What does that even mean? Clutter the websites up with ads?

Out of curiosity, how do you link all those accounts to the same person?
No, no. "Monkeys were not to have flown out of my butt."
